chasing duct work blockage

I work in a hospital, a few days ago we had a interesting coincidence we had to test a fire door later in the day we had a comlaint of no cooling in some areas. we found we were not getting air past a certian area so we started looking at smoke and fire dampers and fornd the a airline blown off a air actuator. Now my question is there a better way look for a blockage or do you do the same thing we had to do just start moving celing tile and chasing the duct work?

With Pneumatic there is little you can do but to trace out the lines to find the failure with a BAS system with the appropriate points you can find the location through point failures or duct pressure readings if this is monitored or temp sensor monitors. Also if it is a hybrid system you may be able to use the BAS to pinpoint the point of failure.
